The MDF will eventually become what I used to make a mold. At that point, I will be using epoxy granite to make the base. For now, it'll be mass loaded MDF layers. The platter is currently 5" thick solid aluminum but I may be playing around with some mass loading options there, as well to get the weight out near the perimeter in some fashion. The platter is sitting next to my first DIY turntable that used rekokut K33H parts (platter, motor, bearing)

8 of them will end up in the base, the other two will probably be used as patterns to create more pieces that will hold the amplifier and frequency generator for the AC Sync motors, and an expansion tank for the pump system for the air bearing arm. I'm planning on making the tank and amp integrated into the stand.

I machined the aluminum platter. It's not really done yet but I cleaned off the nastiness from chunk of scrap aluminum that I started with.
